Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Specific dimensions, materials, numerical values, etc. shown in such embodiments are merely examples for facilitating the understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same functions and configurations are denoted by the same reference numerals to omit redundant explanations, and elements not directly related to the present invention are not shown.

[0010] <Configuration of Vehicle> With reference to FIGS. 1 to 3, the configuration of a vehicle 1 according to an embodiment of the present invention will be described.

[0011] FIG. 1 is a schematic diagram showing a schematic configuration of the vehicle 1. As shown in FIG. 1, the vehicle 1 includes an engine 11, a transmission 12, a differential device 13, drive wheels 14, a shift change device 15, a shift position sensor 16, an operation load sensor 17, a load change device 18, and a control device 19.

[0012] The engine 11 generates power using fuel such as gasoline. The engine 11 outputs power for driving the drive wheels 14. The output shaft of the engine 11 is connected to the transmission 12. The power output from the engine 11 is transmitted to the transmission 12.

[0013] The transmission 12 has a plurality of shift speeds. The output shaft of the transmission 12 is connected to the differential device 13. The power transmitted to the transmission 12 is shifted in rotational speed at a gear ratio corresponding to each shift speed by the transmission 12 and then transmitted to the differential device 13.

[0014] The power transmitted to the differential device 13 is distributed by the differential device 13 to a pair of left and right drive wheels 14. Note that the drive wheels 14 may be front wheels or rear wheels. Also, the power output from the engine 11 may be transmitted to both the front wheels and the rear wheels. In that case, the output shaft of the transmission 12 is connected to a front differential device that distributes power to a pair of left and right front wheels and a rear differential device that distributes power to a pair of left and right rear wheels.

[0015] The shift change device 15 is a device for switching the shift speed of the transmission 12. The shift change device 15 is provided with a shift lever 15a. The shift lever 15a receives a shift operation by the driver, which is an operation for switching the shift speed of the transmission 12. The shift lever 15a corresponds to an example of the operation unit according to the present invention.

[0016] The shift lever 15a moves in response to a shift operation by the driver. By switching the shift position, which is the position of the shift lever 15a, the gear stage of the transmission 12 is switched to the gear stage corresponding to the shift position. The operation of moving the shift lever 15a to switch the shift position corresponds to the shift operation.

[0017] FIG. 2 is a schematic diagram showing an example of the shift positions of the shift change device 15. In the example shown in FIG. 2, the shift positions include a first range P1, a second range P2, a third range P3, a fourth range P4, a fifth range P5, and a reverse range PR. The transmission 12 has, as gear stages, a first gear stage, a second gear stage, a third gear stage, a fourth gear stage, a fifth gear stage, and a reverse gear stage.

[0018] The first range P1, the second range P2, the third range P3, the fourth range P4, the fifth range P5, and the reverse range PR respectively correspond to the first gear stage, the second gear stage, the third gear stage, the fourth gear stage, the fifth gear stage, and the reverse gear stage. When the gear stage is the first gear stage, the second gear stage, the third gear stage, the fourth gear stage, or the fifth gear stage, power in the direction of moving the vehicle 1 forward is transmitted to the drive wheels 14. The gear ratios decrease in the order of the first gear stage, the second gear stage, the third gear stage, the fourth gear stage, and the fifth gear stage. When the gear stage is the reverse gear stage, power in the direction of moving the vehicle 1 backward is transmitted to the drive wheels 14.

[0019] The shift position sensor 16 detects the shift position and outputs the detection result to the control device 19. The shift position sensor 16 is provided in the shift change device 15.

[0020] The operation load sensor 17 detects the operation load, which is the load applied to the shift lever 15a by the driver during the shift operation, and outputs the detection result to the control device 19. The operation load sensor 17 is provided in the shift change device 15.

[0021] The load changing device 18 changes the operating load applied to the shift lever 15a by the driver during a shift operation. For example, the load changing device 18 is a device that applies a load to the shift lever 15a. As such a device, for example, an electric actuator such as a motor, or a hydraulic actuator can be used.

[0022] For example, the load changing device 18 applies a load to the shift lever 15a in the same direction as the moving direction of the shift lever 15a during a shift operation. In this case, the direction of the load applied to the shift lever 15a by the load changing device 18 becomes the same as the direction of the driver's operating load. Thereby, the shift operation becomes lighter, and as a result, the operating load by the driver can be reduced. Also, for example, the load changing device 18 applies a load to the shift lever 15a in the direction opposite to the moving direction of the shift lever 15a during a shift operation. In this case, the direction of the load applied to the shift lever 15a by the load changing device 18 becomes opposite to the direction of the driver's operating load. Thereby, the shift operation becomes heavier, and as a result, the operating load by the driver can be increased.

[0023] In the above, an example where the load changing device 18 is a device that applies a load to the shift lever 15a has been described. However, the load changing device 18 only needs to be a device that changes the operating load, and it may be a device other than a device that applies a load to the shift lever 15a. For example, when a damping force by hydraulic oil acts on the shift lever 15a, the load changing device 18 may be a device that changes the operating load by changing the oil temperature of the hydraulic oil to change the damping force.

[0024] The control device 19 includes one or more processors 19a and one or more memories 19b connected to the processor 19a. The processor 19a includes, for example, a CPU (Central Processing Unit). The memory 19b includes, for example, a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM is a storage element that stores programs and arithmetic parameters used by the CPU. The RAM is a storage element that temporarily stores data such as variables and parameters used in the processes executed by the CPU.

[0025] The control device 19 communicates with each device provided in the vehicle 1 (for example, the transmission 12, the shift position sensor 16, the operation load sensor 17, the load change device 18, etc.). The communication between the control device 19 and each device is realized, for example, using CAN (Controller Area Network) communication.

[0026] FIG. 3 is a block diagram showing an example of the functional configuration of the control device 19. For example, as shown in FIG. 3, the control device 19 includes an acquisition unit 191, a control unit 192, a storage unit 193, and a learning unit 194. Note that various processes including the processes described below performed by the acquisition unit 191, the control unit 192, and the learning unit 194 can be executed by the processor 19a. Specifically, by the processor 19a executing the program stored in the memory 19b, various processes are executed. The function of the storage unit 193 is realized by the memory 19b.

[0027] The acquisition unit 191 acquires various information and outputs it to the control unit 192 and the storage unit 193. For example, the acquisition unit 191 acquires information from the shift position sensor 16 and the operation load sensor 17.

[0028] The control unit 192 controls the operations of each device in the vehicle 1. For example, the control unit 192 can switch the gear stage of the transmission 12 by controlling the operation of the transmission 12. Specifically, the control unit 192 switches the gear stage of the transmission 12 to the gear stage corresponding to the shift position detected by the shift position sensor 16. The gear stage of the transmission 12 is switched, for example, according to a control command output from the control device 19. However, the switching method of the gear stage of the transmission 12 may be a shift-by-wire method as described above, or a mechanical method that is not a shift-by-wire method. Also, for example, the control unit 192 can adjust the operation load of the driver in the shift operation by controlling the operation of the load change device 18.

[0029] The storage unit 193 stores various information. For example, the storage unit 193 stores the information acquired by the acquisition unit 191. The information stored in the storage unit 193 is used for the processes performed by the control unit 192 and the learning unit 194. Note that the learning result by the learning unit 194 described later is also stored in the storage unit 193.

[0030] The learning unit 194 learns the shift operation characteristics, which are the characteristics of the shift operation by the driver. In the present embodiment, the control unit 192 controls the operation of the load change device 18 based on the learning result of the shift operation characteristics by the learning unit 194. Thereby, improvement of the driver's comfort is realized. Details of the shift operation characteristics will be described later.

[0031] <Operation of the vehicle> Subsequently, with reference to FIGS. 4 to 8, the operation of the vehicle 1 according to the embodiment of the present invention will be described.

[0032] As described above, in the present embodiment, the learning unit 194 learns the shift operation characteristics, which are the characteristics of the shift operation by the driver. Hereinafter, the process related to the learning of the shift operation characteristics performed by the learning unit 194 is also referred to as the learning process. Also, as described above, in the present embodiment, the control unit 192 controls the operation of the load changing device 18 based on the learning result of the shift operation characteristics by the learning unit 194. Hereinafter, the process related to the control of the load changing device 18 performed by the control unit 192 is also referred to as the load adjustment process.

[0033] Hereinafter, the learning process performed by the learning unit 194 and the load adjustment process performed by the control unit 192 will be described in this order.

[0034] FIG. 4 is a flowchart showing an example of the flow of the learning process performed by the learning unit 194 of the control device 19. The control flow of the learning process shown in FIG. 4 is repeatedly executed in parallel with or sequentially with respect to the control flow of the load adjustment process shown in FIG. 8 described later, for example.

[0035] When the control flow shown in FIG. 4 is started, first, in step S101, the learning unit 194 learns the shift operation characteristics based on the shift operation information. The shift operation information is information related to the shift operation by the driver. The shift operation information is acquired by the acquisition unit 191, stored in the storage unit 193, and accumulated during the running of the vehicle 1. Examples of the shift operation information will be described later. The shift operation characteristics are the characteristics of the transition of the operation load in the shift operation and are driver-specific characteristics.

[0036] FIG. 5 is a diagram showing an example of the transition of the operating load. In FIG. 5, the vertical axis represents the operating load [N], and the horizontal axis represents the time [s]. In the example of FIG. 5, the shift operation is started at time point T0. That is, at time point T0, the driver starts applying a load to the shift lever 15a and starts moving the shift lever 15a. Then, the operating load increases from time point T0 to time point T1 and reaches the maximum at time point T1. The operating load at time point T1 corresponds to the maximum operating load, which is the value of the operating load when the operating load becomes maximum in the shift operation. Thereafter, after time point T1, the operating load decreases, and at time point T2, the shift operation ends. That is, at time point T2, the application of the load by the driver to the shift lever 15a ends, and the movement of the shift lever 15a ends. Thereby, the shift position is switched to the shift position desired by the driver, and the gear stage of the transmission 12 is switched.

[0037] In step S101, the learning unit 194 learns the shift operation characteristics by using, for example, the maximum operating load and the maximum load reach time as shift operation information. The maximum load reach time is the time from the start point of the shift operation to the point in time when the operating load becomes maximum in the shift operation. In the example of FIG. 5, the maximum load reach time is the time from time point T0 to time point T1. Note that in step S101, for example, the average value of the maximum operating loads and the average value of the maximum load reach times obtained in a predetermined number of past shift operations are used as the shift operation information. The maximum operating load and the maximum load reach time in each shift operation can be generated based on the detection result of the operating load sensor 17 stored in the storage unit 193.

[0038] FIG. 6 is a diagram showing an example of the relationship between the shift operation characteristics, the maximum operating load, and the maximum load reach time. In FIG. 6, the vertical axis represents the maximum operating load [N], and the horizontal axis represents the maximum load reach time [s].

[0039] In the example of FIG. 6, when the maximum operation load is smaller than the reference load and the maximum load arrival time is shorter than the reference time, the learning unit 194 determines the shift operation characteristic C1 as the driver's shift operation characteristic. Further, when the maximum operation load is larger than the reference load and the maximum load arrival time is shorter than the reference time, the learning unit 194 determines the shift operation characteristic C2 as the driver's shift operation characteristic. Further, when the maximum operation load is smaller than the reference load and the maximum load arrival time is longer than the reference time, the learning unit 194 determines the shift operation characteristic C3 as the driver's shift operation characteristic. Further, when the maximum operation load is larger than the reference load and the maximum load arrival time is longer than the reference time, the learning unit 194 determines the shift operation characteristic C4 as the driver's shift operation characteristic. Thus, in the example of FIG. 6, in the learning of the shift operation characteristic, any one of the shift operation characteristics C1, C2, C3, and C4, which are four candidates for the shift operation characteristic prepared in advance, is obtained as the learning result.

[0040] Here, each of the shift operation characteristics C1, C2, C3, and C4 is associated with a transition model of the operation load. The transition model of the operation load is a model that models the transition of the operation load. FIG. 7 is a diagram showing an example of the transition model of the operation load corresponding to each of the shift operation characteristics C1, C2, C3, and C4. In FIG. 5, the vertical axis represents the operation load [N], and the horizontal axis represents the time [s].

[0041] In FIG. 7, a point D1 where the operation load becomes the maximum operation load in the transition model corresponding to the shift operation characteristic C1, a point D2 where the operation load becomes the maximum operation load in the transition model corresponding to the shift operation characteristic C2, a point D3 where the operation load becomes the maximum operation load in the transition model corresponding to the shift operation characteristic C3, and a point D4 where the operation load becomes the maximum operation load in the transition model corresponding to the shift operation characteristic C4 are shown. Comparing points D1, D2 with points D3, D4, it can be seen that in the shift operation characteristics C1, C2, the maximum load arrival time is shorter than that in the shift operation characteristics C3, C4. Further, comparing points D1, D3 with points D2, D4, it can be seen that in the shift operation characteristics C1, C3, the maximum operation load is smaller than that in the shift operation characteristics C2, C4.

[0042] The shift operation characteristic C1 corresponds to, for example, the shift operation characteristic of a driver who prioritizes safety. The shift operation characteristic C2 corresponds to, for example, the shift operation characteristic of a driver who prioritizes the feeling of switching to a desired shift position. The shift operation characteristic C3 corresponds to, for example, the shift operation characteristic of a driver who prioritizes ride comfort. The shift operation characteristic C4 corresponds to, for example, the shift operation characteristic of a driver who prioritizes smooth shift operation.

[0043] In the load adjustment process described below, the operation of the load changing device 18 is controlled so that the operation load changes along the transition model corresponding to the shift operation characteristic learned by the learning unit 194. Thereby, the driver can perform the shift operation with an operation feeling according to his / her preference.

[0044] In the above, an example in which the learning unit 194 determines the shift operation characteristic of the driver from among four candidates for the shift operation characteristic prepared in advance has been described. However, the number of candidates for the shift operation characteristic may be other than four.

[0045] Also, in the above, an example in which the learning unit 194 learns the shift operation characteristic based on two types of shift operation information, the maximum operation load and the maximum load arrival time, has been described. However, the learning unit 194 may learn the shift operation characteristic based on one type or three or more types of shift operation information. Further, the learning unit 194 may learn the shift operation characteristic based on shift operation information other than the maximum operation load and the maximum load arrival time. For example, the learning unit 194 may learn the shift operation characteristic using the total operation time as the shift operation information. The total operation time is the time from the start point of the shift operation to the end point of the shift operation. In the example of FIG. 5, the total operation time is the time from time point T0 to time point T2. In this case, for example, the average value of the total operation time obtained in a predetermined number of past shift operations is used as the shift operation information. The total operation time in each shift operation can be generated based on the detection result of the operation load sensor 17 stored in the storage unit 193.

[0046] Next to step S101 in FIG. 4, in step S102, the learning unit 194 determines whether the shift operation characteristics obtained by learning are different from the registered shift operation characteristics. Here, the shift operation characteristics obtained by the previous learning are stored and registered in the storage unit 193.

[0047] If it is determined that the shift operation characteristics obtained by learning are different from the registered shift operation characteristics (YES in step S102), the process proceeds to step S103, and the learning unit 194 updates the registered shift operation characteristics to the shift operation characteristics obtained by this learning. For example, if the shift operation characteristic C2 is registered as the previous learning result and the shift operation characteristic C1 is obtained as the current learning result, the learning unit 194 updates the registered shift operation characteristics to the shift operation characteristic C1.

[0048] On the other hand, if it is determined that the shift operation characteristics obtained by learning are the same as the registered shift operation characteristics (NO in step S102), the process proceeds to step S104, and the learning unit 194 maintains the registered shift operation characteristics.

[0049] Next to step S103 or step S104, the control flow shown in FIG. 4 ends.

[0050] FIG. 8 is a flowchart showing an example of the flow of the load adjustment process performed by the control unit 192 of the control device 19. The control flow of the load adjustment process shown in FIG. 8 is repeatedly executed in parallel with or sequentially with respect to the control flow of the learning process shown in FIG. 4, for example, as described above.

[0051] When the control flow shown in FIG. 8 is started, first, in step S201, the control unit 192 determines whether the shift operation by the driver has started. The control unit 192 can determine whether the shift operation has started based on the detection result of the operation load sensor 17, for example.

[0052] If it is determined that the shift operation has not been started (NO in step S201), the control flow shown in FIG. 8 ends. On the other hand, if it is determined that the shift operation has been started (YES in step S201), the process proceeds to step S202.

[0053] If it is determined to be YES in step S201, in step S202, the control unit 192 drives the load changing device 18 based on the registered shift operation characteristics. Here, the control unit 192 controls the operation of the load changing device 18 so that the operating load changes along the transition model corresponding to the registered shift operation characteristics.

[0054] For example, when the operating load detected by the operating load sensor 17 is greater than the operating load at the same time point on the transition model, the control unit 192 applies a load in the same direction as the moving direction of the shift lever 15a to the shift lever 15a by the load changing device 18. Thereby, the shift operation becomes lighter, and as a result, the operating load can be brought closer to the transition model. Also, for example, when the operating load detected by the operating load sensor 17 is smaller than the operating load at the same time point on the transition model, the control unit 192 applies a load in the direction opposite to the moving direction of the shift lever 15a to the shift lever 15a by the load changing device 18. Thereby, the shift operation becomes heavier, and as a result, the operating load can be brought closer to the transition model.

[0055] Next to step S202, in step S203, the control unit 192 determines whether the shift operation by the driver has ended. The control unit 192 can determine whether the shift operation has ended based on, for example, the detection result of the operating load sensor 17.

[0056] If it is determined that the shift operation has not ended (NO in step S203), the process returns to step S202. On the other hand, if it is determined that the shift operation has ended (YES in step S203), the process proceeds to step S204.

[0057] If it is determined as YES in step S203, in step S204, the control unit 192 stops the load changing device 18, and the control flow shown in FIG. 8 ends.

[0058] As described above, with reference to FIGS. 4 to 8, an example of the process performed by the control device 19 has been described. However, the control device 19 may perform other processes instead of the processes described above, or may additionally perform processes other than the processes described above.

[0059] For example, an example in which the learning unit 194 determines the shift operation characteristics of the driver from among candidates for shift operation characteristics prepared in advance in the learning process has been described. However, the learning unit 194 may generate the shift operation characteristics of the driver based on the shift operation information in the learning process. Further, the shift operation characteristics to be learned do not necessarily have to be associated with the transition model of the operation load. For example, the control unit 192 may learn the average value of the maximum operation load acquired in the shift operations for a predetermined number of times in the past as the shift operation characteristics, and control the operation of the load changing device 18 so that the maximum operation load in the shift operation matches the learned average value.

[0060] Also, for example, the learning unit 194 may separately learn the shift operation characteristics for each driving location or driving situation. In this case, the shift operation characteristics obtained by learning are stored and registered in the storage unit 193 for each driving location or driving situation. For example, the learning unit 194 may separately learn the shift operation characteristics by dividing them into cases where the driving location is an urban area, a highway, a mountain pass, and a snowy road. For example, in the learning of the shift operation characteristics when the driving location is an urban area, the learning unit 194 learns the shift operation characteristics based on the shift operation information acquired while driving in the urban area. In this way, by separately learning the shift operation characteristics for each driving location or driving situation, the driver can perform the shift operation with an operation feeling that suits his or her preference according to the driving location or driving situation.

[0061] Further, for example, the learning result by the learning unit 194 may be stored in a device on the cloud that can communicate wirelessly with the vehicle 1. Thereby, even when the driver changes to another vehicle and drives, the control unit 192 can control the operation of the load changing device 18 based on the learning result of the shift operation characteristics by the learning unit 194.

[0062] <Effect of the vehicle> Subsequently, the effect of the vehicle 1 according to the embodiment of the present invention will be described.

[0063] In the vehicle 1 according to the present embodiment, the learning unit 194 of the control device 19 learns the shift operation characteristics, which are the characteristics of the shift operation by the driver, based on the shift operation information regarding the shift operation by the driver. Then, the control unit 192 of the control device 19 controls the operation of the load changing device 18 based on the learning result of the shift operation characteristics by the learning unit 194. Therefore, after appropriately learning the shift operation characteristics unique to the driver, the shift operation characteristics can be reflected in the operation load in the shift operation. Thus, the driver can perform the shift operation with an operation feeling that suits his / her preference.

[0064] Further, in the vehicle 1 according to the present embodiment, it is preferable that the shift operation information includes the maximum operation load, which is the value of the operation load when the operation load becomes maximum in the shift operation. Thereby, the shift operation characteristics indicating the driver's preference for the maximum operation load can be appropriately learned. Therefore, the driver's preference for the maximum operation load can be reflected in the operation load in the shift operation.

[0065] Further, in the vehicle 1 according to the present embodiment, it is preferable that the shift operation information includes the maximum load reach time, which is the time from the start point of the shift operation to the point when the operation load becomes maximum in the shift operation. Thereby, the shift operation characteristics indicating the driver's preference for the maximum load reach time can be appropriately learned. Therefore, the driver's preference for the maximum load reach time can be reflected in the operation load in the shift operation.

[0066] In addition, in the vehicle 1 according to the present embodiment, it is preferable that the shift operation information includes the total operation time, which is the time from the start point to the end point of the shift operation. Thereby, the shift operation characteristics indicating the driver's preference for the total operation time can be appropriately learned. Therefore, the driver's preference for the total operation time can be reflected in the operation load in the shift operation.

[0067] In addition, in the vehicle 1 according to the present embodiment, the shift operation characteristics are associated with the transition model of the operation load, and it is preferable that the control unit 192 controls the operation of the load change device 18 so that the operation load changes along the transition model corresponding to the learned shift operation characteristics. Thereby, it is appropriately realized to adjust the transition of the operation load in the shift operation to match the driver's preference. Therefore, it is appropriately realized that the driver performs the shift operation with an operation feeling that matches his or her preference.

[0068] As described above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings. Of course, the present invention is not limited to the above-described embodiments, and it goes without saying that various modification examples or correction examples within the scope described in the claims also belong to the technical scope of the present invention.

[0069] For example, the processes described using flowcharts in this specification do not necessarily have to be executed in the order shown in the flowcharts. In addition, additional processing steps may be adopted, or some processing steps may be omitted.

[0070] For example, in the above, an example where the vehicle 1 is a manual vehicle has been described. However, the vehicle 1 may be an automatic vehicle having a manual mode in which the gear stage is switched according to a shift operation. In that case, in the manual mode, the above-described learning process and load adjustment process can be executed.
